AND is very flexible. The renice intervals can be adjusted as well as the default nice level and the activation intervals. A priority database stores user/group/job/ancestor tuples along with their renice values for three CPU usage time ranges. Negative nice levels are interpreted as signals to be sent to a process, triggered by CPU usage; this way, Netscapes going berserk can be killed automatically. The strategy for searching the priority database can be configured.

AND also provides network-wide configuration files with host-specific sections, as well as wildcard/regexp support for commands in the priority database.
